"Air Force testing new transparent armor

10/17/2005 - WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFPN) -- Engineers here
are testing a new kind of transparent armor -- stronger and lighter than
traditional materials -- that could stop armor-piercing weapons from
penetrating vehicle windows.

The Air Force Research Laboratorys materials and manufacturing directorate
is testing aluminum oxynitride -- ALONtm -- as a replacement for the
traditional multi-layered glass transparencies now used in existing ground
and air armored vehicles.
[...]

ALONtm is a ceramic compound with a high compressive strength and
durability. When polished, it is the premier transparent armor for use in
armored vehicles, said. 1st Lt. Joseph La Monica, transparent armor
sub-direction lead
[...]
Traditional transparent armor is thick layers of bonded glass. The new armor
combines the transparent ALONtm piece as a strike plate, a middle section
of glass and a polymer backing. Each layer is visibly thinner than the
traditional layers.

ALONtm is virtually scratch resistant, offers substantial impact resistance,
and provides better durability and protection against armor piercing
threats, at roughly half the weight and half the thickness of traditional
glass transparent armor, said the lieutenant.

In a June 2004 demonstration, an ALONtm test pieces held up to both a .30
caliber Russian M-44 sniper rifle and a .50 caliber Browning Sniper Rifle
with armor piercing bullets. While the bullets pierced the glass samples,
the armor withstood the impact with no penetration.
